Intake Manifold: Description and Operation
INTAKE MANIFOLD
DESCRIPTION
The aluminum intake manifold (Fig. 68) is a single plane design with equal length runners and uses a separate plenum, therefore the manifold does
have a plenum gasket. It also uses separate flange gaskets and front and rear cross-over gaskets. Extreme care must be used when sealing the gaskets to
ensure that excess sealant does not enter the intake runners causing a restriction. Whenever the intake manifold is removed inspect the plenum pan for
evidence of excess oil buildup, this condition indicates that the plenum pan gasket is leaking.
OPERATION
The intake manifold, meters and delivers air to the combustion chambers allowing the fuel delivered by the fuel injectors to ignite, thus producing
power.
